That would explain why it didn't work for you.

Yes, "C-x RET c" should be typed immediately before opening the file,
because its effect lasts for one command only.

Yes.

Emacs 21.1 was released  several months ago.  I didn't release its
DJGPP port because I wasn't sure it was stable enough (the N.0
version problem).  However, anyone can download the official GNU
distribution from ftp.gnu.org and build it with DJGPP.  The DJGPP
build is supported right out of the box, just read the file INSTALL
for instructions.

It depends on what machine I'm working.  This one runs the development
version of Emacs, straight out of the CVS tree.

Yes.

I think the best is to read the 8-bit characters as users on Unix
are.  That's what "C-x RET c latin-1 RET" should have let you do.

> I guess I should not set-terminal-coding-system in DOS?

It only makes sense to do that if you change the codepage.
Otherwise, Emacs sets the correct terminal encoding at startup, by
looking at your codepage.

> same buffer with DOS Emacs?

Yes.  If you want to see how it looks like, type "C-h H".  It will
display a file that says Hello in several languages.  I doubt that
there is any other DOS editor that can display this file reasonably
well (expect the Far-Eastern languages to be displayed with empty
boxes instead of the hieroglyphs, which only work on Far-Eastern DOS
and Windows machines).
